Duplex feeder with side shifting inversion

摘要: Automatic printing machine for producing successive duplex prints has means (22, 23, 12) forming an image on a print substrate, feeding substrates (31) to said form first side of substrates, and (41, 42, 40) defining substrate transport path having images the opposite substrate. The includes invert each twice about axis perpendicular direction path, shifting inverter (40) once parallel direction. comprises guide comprising top sheet insertion baffle (44) bottom (45) portion one baffles at least aperture therein, rotatable segmented drive roll (51) flat curved portion, extending through when is rotated be in driving engagement with remaining baffle, not adjacent aperture. also reversing arcuate around (62) means. In preferred embodiment removable cassette which interchangeable cassette.
